# f_variable_new $handle $variable

|

# Register a new variable named $variable with the given reference-handle

# $handle. The environment variable $handle is set to $variable allowing you to
|
|
# use the f_getvar() function (from common.subr) with $handle to get the value
|
|
# of environment variable $variable. For example:
|
|
#
|
|
# f_variable_new VAR_ABC abc
|
|
#
|
|
# allows the later indirection:
|
|
#
|
|
# f_getvar $VAR_ABC
|
|
#
|
|
# to return the value of environment variable `abc'. Variables registered in
|
|
# this manner are recorded in the $VARIABLES environment variable for later
|
|
# allowing dynamic enumeration of so-called `registered/advertised' variables.
